Let’s go step by step to match each definition with the correct quadrilateral.
---
1. All sides are the same length. There are four right angles.
→ This describes a
square.
A square has 4 equal sides and 4 right angles (90°).
Look at the options:
e. Square matches this.
✔ Answer for #1:
e
---
2. There is only one pair of parallel sides.
→ That’s the definition of a
trapezoid.
Only one pair of opposite sides is parallel.
Option
c. Trapezoid shows that shape.
✔ Answer for #2:
c
---
3. Opposite sides are parallel and the same length. There are four right angles.
→ This is a
rectangle.
Opposite sides equal and parallel, all angles 90°.
Option
b. Rectangle fits.
✔ Answer for #3:
b

4. There are two pairs of parallel sides. All sides are the same length.
→ Two pairs of parallel sides = parallelogram family.
All sides same length → that’s a
rhombus.
Note: A rhombus doesn’t need right angles — just equal sides and parallel opposites.
Option
d. Rhombus matches.
✔ Answer for #4:
d
---
5. There are two pairs of opposite parallel sides.
→ This is the basic definition of a
parallelogram.
It doesn’t say anything about side lengths or angles — just two pairs of parallel sides.
Option
a. Parallelogram is correct.
✔ Answer for #5:
a

6. List two ways a rectangle and square are alike and one way in which they are different.
Let’s think:
Alike:
- Both have 4 right angles.
- Both have two pairs of parallel sides.
*(You can pick any two of these — also both are quadrilaterals, both have opposite sides equal, etc.)*
Different:
- In a square, ALL four sides are equal. In a rectangle, only opposite sides are equal (length ≠ width usually).
So we can write:
> Alike:
> - Both have four right angles.
> - Both have two pairs of parallel sides.
> Different:
> - A square has all sides equal; a rectangle does not (only opposite sides are equal).
---
Final Answer:
1. e
2. c
3. b
4. d
5. a
6. Alike: Both have four right angles and two pairs of parallel sides. Different: A square has all sides equal, but a rectangle only has opposite sides equal.
